Great concept like Jason said, but this needs a lot of work and substantially more input from truly knowledgeable sources.
I'm sorry Ben, I like a lot of your work, but I wouldn't even call this an introductory remedial course... but more so a dangerous, inaccurate, and misguided document for the otherwise unaware.

As a side note, I hope the same grainy and imperceptible images aren't used on the $500 version of this...

Lemme guess.... They had that Infrared Certified guy give all of the input and didn't consult with any of the real thermographers that have been commenting??? What a waste of talent....

Again, send me at [email protected] any errors that you may find in any course, and we'll make the necessary changes.

InterNACHI as a matter of practice reviews course content and instructional design and delivery. Updates and revisions are based upon those reviews and the continual, day-to-day maintenance and editing of the content as issues arise.

Also consider a painted surface vs. a non painted
surface will affect the same material and
cause different emissivity.

The last 3 words in that sentence has me confused. Someone please explain... perhaps we need to go back to the beginning at page 5 to find the definition of emissivity... oh... that's right... it wasn't really defined. Hopefully that will be in the $500 version though.
